How delete "?" from url with .htaccess?

@vinnie 

To remove the question mark "?" from a URL using .htaccess, you can use the following code:

1
2
3

RewriteEngine On
RewriteCond %{QUERY_STRING} .
RewriteRule ^ %{REQUEST_URI}? [L,R=301]

This code will redirect any URL that contains a question mark to the same URL without the question mark. The [L,R=301] flag at the end of the RewriteRule line indicates a permanent redirect, and the trailing ? in the substitution string removes the query string.
